Mastering Conjuration means having access to an entire spectrum of utility. —Are you in need of a flame spell? Conjure a Flame Atronach. You'll have command of a dozen such spells, in the form of a fiery avatar. —Are you caught in the dead of night and wishing you had prepared a light spell? Conjure a Will-o-the-Wisp: its natural luminescence banishes darkness. —Is your life detection spell unable to discern a fleeing target from all the other living things in the wilderness? Conjure a Wolf Familiar to pick up the scent.
